Massey ferguson 88 clutch

[Claym]

Hello I just purchased a Mf 88 that has
Been sitting for 10 yrs. got it running
Really good but noticed problem with
Clutch. There is no spring back in it
I haven't tried to go in gear while
Running yet . Is there an inspection
Plate on bottom of tractor or does the
Tractor need to be split. Thanks
